As a surface of the walls ( 50   a   , 50   b ) is constituted at the upstream side of flow channel ( 26 ) from a south-pole magnet magnetized between 0.2 mT and 1.5 mT, south-pole magnetism can be efficiently applied to the liquid fuel, and combustion efficiency of heat engine of diesel vehicles, gasoline vehicles, LP gas-fueled vehicles, vessels, boilers etc. can be increased and all noxious substances in exhaust gas such as CO 2 , CO, HC. NO x , PM, etc can be considerably reduced.

TECHNICAL FIELD

This application relates to a device for processing liquid fuel whereinnoxious substances such as CO, CO₂, HC, NO_(x), PM in exhaust gasemitted from heat engines used in diesel vehicles, gasoline-fueledvehicles, LP gas-fueled vehicles, vessels, diesel generators and boilerscan be substantially reduced.

BACKGROUND ARTS

Heretofore, magnetic processing is known to be effective in saving fuelconsumption in heat engines used in diesel vehicles, gasoline-fueledvehicles, LP gas-fueled vehicles, ships and vessels, diesel generatorsand boilers. At the same time, other such approaches seem to be oftenattempted. However, such proposals and approaches lacked certainty andstability in their outcomes, and thus they have not been commercializedon an industrial basis.

On the other hand, no stable effect in improvement of fuel efficiencyand in reduction of noxious substances in exhaust gas could have beenobtained from a device using ordinarily available magnet when it wasmounted on an automobile in order to be subject to a running test.

The inventor of the present application found that significant effect ofaround 30% of fuel saving can be obtained when magnet having variousfeatures are manufactured (see for example Patent Document 1), fromwhich a device for processing liquid fuel is fabricated and mounted on avehicle in order to perform a running test, and confirmed withreproducibility that CO, CO₂, HC, NO_(x) and PM can be substantivelyreduced as a result of diesel emission 13-mode cycle test with a dieselvehicle for example. Furthermore, it is disclosed that fuel efficiencyimprovement effect can be obtained by applying south-pole magnetism toliquid fuel (for example in Patent Document 1).

However, mass production of conventional metal specialty magnet wasdifficult and thus commercialization on an industrial basis could nothave been easily done.

Furthermore, a configuration for applying south-pole magnetism to liquidfuel more efficiently and specific settings therefor were not clarified.

MODE FOR WORKING THE INVENTION Embodiment 1

FIG. 1 is a cross-sectional view showing an embodiment mode of a devicefor processing liquid fuel according to this invention. Besides, FIG. 2is an exploded perspective view of a wall for applying magnetism used inthe device for processing liquid fuel according to this invention, andFIG. 3 is an A-A cross-sectional view of the device for processingliquid fuel according to this invention. The device (10) for processingliquid fuel increases combustion efficiency in heat engines, etc. byapplying south-pole magnetism to liquid fuel to reduce fuel consumption,and is used for reducing the amount of noxious substances (CO, CO₂, HC,NO_(x) and PM) in exhaust gas emitted from these heat engines, etc.Device (10) for processing liquid fuel is connected in the intermediateof a pipe for providing fuel from fuel tank to heat engines such asengine, for example.

Besides, liquid fuel in this application is referred to as fuels mainlycomposed from carbon hydride, for example petroleum fraction, coalcarbonization and cracked petroleum, or heavy oil, light oil, gasolineetc., and biofuel.

Now, effect of applying south-pole magnetism to liquid fuel isexplained.

By applying south-pole magnetism to liquid fuel, molecular group(cluster) consisting that liquid fuel can be minified. Therefore, asspraying condition is improved by using south-pole magnetism appliedliquid fuel, combustion speed can be accelerated and as a result,combustion efficiency can be increased.

On the other hand, while liquid fuel is sprayed from a spray nozzle in aliquid fuel combustion chamber in the heat engines, etc., nozzle hole isnarrowed when insoluble substances such as impurities contained inliquid fuel etc. adhere to spray nozzle, and spraying condition isdeteriorated. Furthermore, while static electricity generates againstimpurities, etc. when liquid fuel circulates in the pipes, as thoseimpurities, etc. have a characteristic they adhere to south-polemagnetism but not to north-pole magnetism, insolvable substances can beseparated and removed by making us of this characteristic. Therefore, byapplying south-pole magnetism to liquid fuel, adhesion of impurities tospray nozzle can be prevented so as to restore spraying condition, andas a result combustion efficiency can be improved.

This device (10) for processing liquid fuel is composed of main bodyportion (20), inhaling side surface (30), discharging side surface (40),walls (50 a, 50 b) for applying magnetism, and fixing member (70) forwall for applying.

The main body portion (20) constitutes the exterior part of the device(10) for processing liquid fuel with the inhaling side surface (30) andthe discharging side surface (40), and is provided for holdinginternally walls (50 a, 50 b) for applying magnetism and fixing member(70) for wall for applying. The main body portion (20) is formed, forexample in a tubular form the cross-sectional surface of which iscircular, and is molded by a magnetic container of metal. Furthermore, afirst opening portion (22) and a second opening portion (24) are formedat the inhaling side (upstream side) and discharging side (downstreamside) of the main body portion (20). And inside the main body portion(20), flow channel (26) is formed in which liquid fuel circulates. Inthe present embodiment, the main body portion (20) is formed for exampleat 60 mm in external diameter, 55 mm in internal diameter and 140 mm inlength. Moreover, the main body portion (20) is not limited to a tubularform the cross-sectional surface of which is circular as in the presentembodiment, but can be in any form such as a quadrangulercross-sectional surface, etc.

The inhaling side surface (30) is formed for blocking the openingportion at the inhaling side in the main body portion (20). The inhalingside surface (30) is formed at a dimension roughly isomorphic to thefirst opening portion (22) at the inhaling side, and is tightlyappressed by welding for example to the first opening portion (22) atthe inhaling side of the main body portion (20). At a rough center ofthe inhaling side surface (30), an inhaling portion (32) is formed.Inhaling portion (32) is provided for example in order to inhale liquidfuel provided from the fuel tank into the device 10 for processingliquid fuel. Inhaling portion (32) is formed in a form in which a pipefor liquid fuel provided from fuel tank is connectable.

Furthermore, discharging side surface (40) is formed for blocking thesecond opening portion (24) at the discharging side in the main bodyportion (20). Discharging side surface (40) is formed at a dimensionroughly isomorphic to the second opening portion (24) at the dischargingside, and is tightly appressed by welding for example to the secondopening portion (24) at the discharging side of the main body portion(20). Furthermore, at a rough center of the discharging side surface, adischarging portion (42) is formed. Discharging portion (42) is providedfor example in order to discharge liquid fuel from the device (10) forprocessing liquid fuel into heat engine. Discharging portion (42) isformed in a form in which a pipe for providing liquid fuel into heatengine is connectable.

By forming inhaling hole (32) and discharging hole (42) at respectiverough centers of the inhaling side surface (30) and the discharging sidesurface (40), device (10) for processing can be stably fixed wheninstalled on a pipe. Furthermore, inhaling side surface (30) anddischarging side surface (40) can be easily worked.

On the flow channel (26) formed inside the main body portion (20), aplurality of walls (50 a, 50 b) for applying magnetism will be arrangedin order to apply south-pole magnetism to liquid fuel provided to thedevice (10) for processing liquid fuel according to this invention.Subsequently, positioning relationships in the main body portion (20) ofwalls (50 a, 50 b) for applying magnetism are explained in details.

The main body portion (20) has an upper surface and a bottom surfaceopposing each other at a distance in a direction perpendicular to shaftcore direction (in the direction of the diameter). Wall (50 a) forapplying magnetism is projected from one surface to the other surface ina roughly perpendicular way. A space is provided as pathway (52 a)between the wall (50 a) for applying magnetism and the other surface.Furthermore, wall (50 b) for applying magnetism is projected from theother surface to the one surface in a roughly perpendicular way. A spaceis provided as pathway (52 b) between this wall (50 b) for applyingmagnetism and the one surface. Then, wall (50 a) for applying magnetismand wall (50 b) for applying magnetism are alternately arranged with anadequate interval in the shaft core direction.

In other words, walls (50 a, 50 b) for applying magnetism are arranged,for example in a perpendicular direction against the direction of liquidfuel flow channel. Meanwhile, the installation interval of walls (50 a,50 b) for applying magnetism can be between 1 mm and 35 mm, while it isparticularly preferable that the walls are installed at an interval of10 mm. Furthermore, when safety is considered, it is preferable thatwalls (50 a, 50 b) for applying magnetism are installed at an intervalnot smaller than 2 mm. In case the main body portion (20) is formed in atubular form as in this embodiment, it is preferable that walls (50 a,50 b) for applying magnetism are installed at an interval roughly equalto the internal diameter of inhaling portion (32) and dischargingportion (42). Thereby, flow volume of liquid fuel circulating within thedevice (10) for processing liquid fuel can be stabilized. Meanwhile, incase the walls (50 a, 50 b) for applying magnetism are installed at aninterval greater than the internal diameter of inhaling portion 32 anddischarging portion 42, liquid fuel inhaled in the device (10) forprocessing liquid fuel risks to be mixed with already inhaled liquidfuel.

As a result, in the walls (50 a, 50 b) for applying magnetism, pathways(52 a, 52 b, 52 c, 52 d) are formed such that liquid fuel flows in themain body portion (20) in a zigzag manner between the walls (50 a, 50b). Pathways (52 a, 52 b, 52 c, 52 d) are provided such that at least adimension of one tenth to three tenth of the diameter of the main bodyportion (20) is ensured. In other words, in pathways (52 a, 52 b, 52 c,52 d), the dimension in the direction perpendicular to the direction ofthe flow channel is preferably formed in a dimension greater than theinternal diameter of inhaling portion (32) and discharging portion (42).Thus, flow volume of the liquid fuel circulating in the device (10) forprocessing liquid flow can be stabilized. In this embodiment, pathways(52 a, 52 b, 52 c, 52 d) are formed by parallel cutting walls (50 a, 50b) for applying magnetism at approximately two-third from its center.Furthermore, dimension of pathways (52 a, 52 b, 52 c, 52 d) areappropriately modifiable depending on the flow volume of the liquidfuel. Moreover, walls (50 a, 50 b) for applying magnetism are arrangedsuch that liquid fuel does not circulate in any place other thanpathways (52 a, 52 b, 52 c, 52 d). Walls (50 a, 50 b) for applyingmagnetism are composed of magnetism applying portions (54, 54) andnonmagnetic portion (60). Furthermore, magnetism applying portion (54)is further composed of magnet (56) and magnet holding member (58).

Magnet (56) is provided such that one surface (51 a) and other surface(51 b) of walls (50 a, 50 b) for applying magnetism are south-polemagnetized. That is to say that it is provided such that top surfaces(56 a, 56 a) of the magnets (56, 56) are south-pole magnetized and backsurfaces (56 b, 56 b) are north-pole magnetized. Therefore, top surface(54 a) of the magnetism applying portion (54) is south-pole magnetizedand back surface (54 b) is north-pole magnetized. Furthermore, magnet(56) is formed lamellar and roughly round. Magnet (56) is formed frompermanent magnet and in particular from plastic magnet preferably.Meanwhile, magnet (56) can be other resins or synthetic rubber if thematerial is not oil-soluble. By using such magnet, magnet (56) can befreely molded and mass-produced, and as mass-production in compact sizeis possible, it is particularly preferable. Furthermore, the strength ofmagnetic flux of south-pole magnetism of magnet (56) is preferablybetween 0.2 mT and 1.5 mT and in particular between 0.8 mT and 1.0 mT.Meanwhile, if the strength of magnetic flux is more than 1.5 mT, theimprovement of effectiveness according to the present invention will bedifficult to be found, and if the strength of magnetic flux is less than0.2 mT, the advantage to remove impurities diminishes. The thickness ofmagnet (56) is formed for example between 4 mm and 10 mm. In the presentembodiment, magnet (56) is formed, for example, at 0.8 mT for thestrength of magnet flux, at a diameter of 54 mm and 4 mm thick.

Meanwhile, the form of magnet (56) used in the device for processingliquid fuel according to this invention may either be round orquadrangular, but preferably round in order that compact size, low priceand mass-production are achieved.

Furthermore, as side surfaces of walls (50 a, 50 b) for applyingmagnetism, against which north-pole magnetism is applied by the factthat walls (52 a, 52 b) for applying magnetism are disposed in amagnetic main body portion (20), contact inner wall surface of main bodyportion (20), surfaces on which north-pole magnetism is applied toliquid fuel will be the surfaces of pathways (52 a, 52 b, 52 c, 52 d)only. Therefore, the area in which liquid fuel contact with south-polemagnetized surface will be larger, and in contrast, the area in whichliquid fuel contact with north-pole magnetized surface can be minified.Furthermore, as north-pole magnetism is dispersed by magnet holdingmember (58) and nonmagnetic portion (60) described below, the ratio ofnorth-pole magnetism to south-pole magnetism is formed such that not toexceed 30%. Thereby, south-pole magnetism can be more strongly appliedto liquid fuel. In the present embodiment, for example, when thestrength of south-pole magnetic flux is 0.8 mT, the strength ofnorth-pole magnetic flux is formed at less than 0.3 mT.

Magnet holding member (58) has a role as a case for embedding magnet(56), and is provided in order to lessen north-pole magnetism of magnet(56) by dispersing it. Magnet holding member (58) is formed in aplate-like roughly round form in conformity to the form of thecross-section of main body portion (20). Then, a recess (58 b) is formedat the top surface (58 a) side of the magnet holding member 58 forembedding and supporting the magnet (56). Recess (58 b) is formedroughly identical to the form of the magnet (56). The depth of recess(58 b) is formed roughly identical to the thickness of the magnet (56),and then a recessed portion (56 c) is formed at the side surface (56 c)of the magnet (56) and a projected portion (58 d) is formed at the sidesurface of recess (58 b) of the magnet holding member (58). That is tosay that the magnet (56) is fixed without moving in upward, downward,left or right direction by being embedded in recess (58 b). Furthermore,magnet (56) is disposed at magnet holding member (58) such that topsurface (56 a) of the magnet (56) and top surface (58 a) of the magnetholding member (58) form a same planar surface. Thereby, the flow volumeof liquid fuel is stabilized. Furthermore, in order to further dispersenorth-pole magnetism, the thickness of the side surface of the magnetholding member (58) and the thickness from the base surface to the backsurface (58 c) of the recess (58 b) are formed roughly identical. Thethickness of the magnet holding member (58) functions to adjust theeffect of reducing north-pole magnetism, and is appropriatelymodifiable. In the present embodiment, for example, the magnet holdingmember (58) is formed at 54 mm in diameter and 7 mm thick.

Magnetism applying portion (54) constitutes a member in which north-polemagnetism is reduced (north-pole demagnetized magnet) by combiningmagnet (56) with magnet holding member (58).

Nonmagnetic portion (60) is provided in order to further reducenorth-pole magnetism from magnet (56) applied to the recess (58 b) ofthe magnet holding member (58), and additionally, to connect by thenorth-pole magnetism, without being seriously repulsive between backsurfaces (58 c, 58 c) of the magnet holding members (58, 58).Nonmagnetic portion (60) is arranged between magnetism applying portion(54, 54) and formed into a wall-plate like nonmagnetic body having onesurface (60 a) and other surface (60 b). The thickness of thenonmagnetic portion (60) functions to adjust effect of reducingnorth-pole magnetism, and is appropriately modifiable. In the presentembodiment, for example, nonmagnetic portion (60) is formed at 54 mm indiameter and 6 mm thick.

Fixing member (70) for walls for applying magnetism is formed, forexample circularly by a magnetic metal, and is provided, for example toarrange walls (50 a, 50 b) for applying magnetism at an appropriateinterval. Fixing members (70) for walls for applying magnetism isprovided to fix walls (50 a, 50 b) for applying magnetism inside themain body portion (20), and are arranged at the respective intervals ofa plurality of walls (50 a, 50 b) for applying magnetism. The breadth offixing member (70) for walls for applying magnetism functions to adjustthe number and interval of walls (50 a, 50 b) for applying magnetism tobe arranged, is appropriately modifiable, and preferably formed in adimension roughly identical to that of the internal diameter of inhalingportion (32) or discharging portion (42). Thereby, the flow volume ofliquid fuel circulating within the device (10) for processing liquidfuel will be stabilized. In the present embodiment, for example, fixingmember (70) for walls for applying magnetism is formed at 54 mm indiameter, 48 mm in internal diameter and 6 mm thick.

Meanwhile, in case the length in the longitudinal direction of the mainbody portion (20) exceeds 140 mm, a device for processing liquid fuelwherein walls (50 a, 50 b) for applying magnetism are respectively in anumber of more than 2 and are arranged at an interval of less than 35 mmis preferable.

Next, a mechanism to apply south-pole magnetism to liquid fuel providedto device (10) for processing liquid fuel according to the presentinvention is described.

First, liquid fuel inhaled from inhaling portion (32) contactsperpendicularly to one surface (51 a) of wall (50 a) for applyingmagnetism and south-pole magnetism is applied to the liquid fuel. Then,the said liquid fuel flows in the direction of pathway (52 a).Subsequently, the said liquid fuel flows into the interval between othersurface (51 a) of the wall (50 a) for applying magnetism and othersurface (51 b) of the wall (50 b) for applying magnetism, and south-polemagnetism from one surface (51 a) of the wall (50 b) for applyingmagnetism and other surface (51 b) of the wall (50 a) for applyingmagnetism is applied to the said liquid fuel. Furthermore, the liquidfuel flows into the next pathway (52 b), and subsequently, south-polemagnetism is applied to the liquid fuel until the liquid fuel isdischarged from the discharging portion (42), and thereafter, flowsbetween one surface (51 a) of the wall (50 a) for applying magnetism andother surface (51 b) of the wall (50 b) for applying magnetism tosequentially flow into pathway 52 c and pathway 52 d, and the liquidfuel is discharged from discharging portion (42).

As stated above, as areas to which south-pole magnetism is applied isexpanded by disposing on the pathway of the liquid fuel, a plurality ofwalls (52 a, 52 b) for applying magnetism in which south-pole magnetismis applied to one surface (51 a) and other surface (51 b) and byconfiguring such that the liquid fuel efficiently flows between thesewalls, south-pole magnetism can be efficiently applied to liquid fuels.

FIG. 4 is a cross-sectional view showinganother embodiment of the device for processing liquid fuel according tothis invention. This device (110) for processing liquid fuel isconfigured by combining wall (50 a) for applying magnetism and magnetismapplying portions (54). That is to say that, the device (110) forprocessing liquid fuel according to this invention disposes wall (50 a)for applying magnetism at a rough median in the longitudinal directionof the main body portion (20), and disposes a plurality of magnetismapplying portions (54) between the inhaling side surface (30) and wall(50 a) for applying magnetism and between discharging side surface (40)and wall (50 a) for applying magnetism. These wall (50 a) for applyingmagnetism and magnetism applying portion (54) are, as in the case ofdevice (10) for processing liquid fuel, fixed by the fixing member (70)for walls for applying magnetism. Magnetism applying portion (54), whichis arranged at the inhaling side surface (30) side with regard to thewall (50 a) for applying magnetism, is arranged such that the south-polemagnetism of the magnet (56) is oriented toward inhaling side surface(30), and magnetism applying portion (54) which is arranged at thedischarging side surface (40) side, is arranged such that the south-polemagnetism of the magnet (56) is oriented toward discharging side surface(40).

FIG. 5 shows a further embodiment of a device for processing liquid fuelaccording to this invention, (a) being a sectional front view and (b)being a planar sectional view. This device (210) for processing liquidfuel disposes on allover the respective sides of base surface (82) andside surface (84) of the fuel tank (80) the wall (50 a) for applyingmagnetism or the magnetism applying portion (54). In this embodiment,magnetism applying portion (54) is disposed on allover the respectivesides of base surface (82) and side surface (84), and the back surface(54 b) of the magnetism applying portion (54) is adhered to base surface(82) and side surface (84). Therefore, in the fuel tank (80), magnetismapplying portion (54) is provided such that the south-pole magnetismapplies inward. Furthermore, at the rough center portion when viewedplanarly, fuel feed pipe (86) is installed upright. Then, inlet (86 a)which is one edge of the fuel feed pipe (86) is provided such as to beinstalled closely to the base surface (82). Therefore, in case theliquid fuel is discharged from fuel feed pipe (86) through theintermediary of inlet (86 a), a pathway (226) is formed which arisesfrom the side surface (84) along the base surface (82) and is orientedtoward the inlet (86 a). Furthermore, magnetism applying portion (54) isarranged radially from the inlet (86 a). Thus, south-pole magnetism isefficiently applied to the liquid fuel discharged through fuel feed pipe(86).

FIG. 6 shows a further embodiment of a device for processing liquid fuelaccording to this invention, (a) being a sectional front view and (b)being a planar sectional view. This device (310) for processing liquidfuel arranges the wall (50 a) for applying magnetism or the magnetismapplying portion (54) such that they touch a base surface (182) of thefuel tank (180).

At a rough center portion when viewed planarly, fuel feed pipe (86) isinstalled upright. Then, inlet (86 a) which is one edge of the fuel feedpipe (86) is provided such as to be installed closely to the basesurface (182). Therefore, in case the liquid fuel is discharged fromfuel feed pipe (86) through the intermediary of inlet (86 a), a pathway(326) is formed which arises from the side surface (84) along the basesurface (182) and is oriented toward the inlet (86 a). Furthermore, wall(50 a) for applying magnetism abuts against base surface (182) such asto surround fuel feed pipe (86). In this embodiment, fuel feed pipe (86)abut against 4 walls (50 a, . . . , 50 a) in 4 directions and furtherabuts against 4 walls (50 a, . . . , 50 a) for applying magnetism in 4directions around them. Thereby, as liquid fuel discharged through fuelfeed pipe (86) circulates between walls (50 a, 50 a) for applyingmagnetism arranged perpendicular to the direction of the flow channel(326) such as to block it, south-pole magnetism is efficiently appliedto the liquid fuel.

The test car utilized in Test Example 2 was used for approximately 18years, and had 26,000 km on the odometer. A device (110) for processingliquid fuel was mounted on the said test car, and a diesel emission13-mode cycle test was performed in a test laboratory designated by theMinistry of Land, Infrastructure, Transport and Tourism. However, as theMinistry of Land, Infrastructure, Transport and Tourism has no data ofdiesel emission 13-mode cycle test for this car model and thuscomparison was impossible, the result obtained from this test wascompared to the emission regulation value at 1994 (effective for 11years from 1994) for a car the gross vehicle weight of which is morethan 2.5 t. Though we could confirm that CO, HC, NO_(x), PM areconsiderably reduced compared to the test at the time when the car wasnew, a comparison for CO₂ could not be performed as a data for the timewhen the car was new was not available. Apparatus for testing, chassisdynamometer was manufactured by Ono Sokki Co., Ltd, and emissionanalyzer, constant volume sampling apparatus, and dilution tunnel wasmanufactured by HORIBA, Ltd. The comparison result is shown in Table 4.
